The Gullagaloona Backpackers arrive in London to collect their inheritance from their founder. They fortuitously stumble across the Winjin' Pom and get him working. However, two gangsters, Ronnie and Reggie Crow are themselves after the van, having left something in it.
The loot left by the Crows inside the Pom turns out to be an old, scratched record of a famous Australian opera singer. After being wrongly put in jail, the Gullagaloona backpackers set off to return the stolen item to its rightful owner.
The travellers decide to sell the Pom after he puts them in trouble with a duo of vicious bull bikers, thus replacing him with a similar-looking campervan.
The backpackers arrive at a spooky mansion. However, Ronnie and Reggie have followed them, trying to get their hands once more on the campervan.
While being chased by the Crows, the Pom hides in a scrapyard. However, the vehicle is accidentally placed in an incinerator.
The Crows kidnap Adelaide as part of a plan by J.G. Chicago to lure the backpackers and Pom into a trap. Afterwards, the vulture cajoles the campervan into working for him. Will he realise where his true loyalties lie?
